FINGER-RING.

No. 795,382. l

To all whom, it may concern.-

Be it known that I, FRED M. ALLEN, a citizen of the United States, residing' at Auburn, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Finger-Rings, of which the following' is a specification.

This invention has reference to an improvement in linger-rings, and more particularly to an improvement in detachable signet-plate linger-rings.

The object of my invention is to improve the construction of detachable or interchangeable signet-plate linger-rings, whereby the signet-plate is positively locked in the ring and readily detached from the ring when required without the use of a special tool for the purpose.

My invention consists in the peculiar and novel construction of a finger-ring Vhaving' an oval box-shaped head in the bottom of which, adjacent one end, is .an off-center hole, an internal annular ledg'e on the side wall of the head having an off-center opening, one side of which is beveled adjacent the hole in the bottom of the head, a sig'net-plate shaped to lit the head and rest on the annular ledge, said plate being adapted to have a letter or monogram on its face, and a spring-wire locking-arm rigidly secured adjacent one end to the under side of the plate in a position for the fixed end to first enter under the ledge and then for the free end to engage with the beveled edge of the opening in the ledge and snap under the ledge through the opening, thus locking the plate to the ring, as will be more fully set forth hereinafter.

Figure l is a side View of myimproved fing'er-ring'. Fig'. 2 is a face view of the ring, showing the detachable signet-plate. Fig. 3 is a transverse sectional view taken on line 3 3 of Fig. l looking at the under side of the head. Fig. @L is an under side view of the signet-plate removed from the ring and showing the spring-wire locking-arm. Fig. 5 is an enlarged sectional view taken on line 5 5 of Fig. 1 through the head, showing the locking-arm in the head in the locked position. Fig. 6 is an enlarged sectional view taken lengthwise through the head on line 6 6 of Fig. 2, showing the signet-plate locked in the head of the ring; and Fig'. 7 is an enlarged detail sectional View taken on line 7 7 of Fig'. 2, showing the means for unlocking' and removing' the signet-plate from the ring.

Specification of Letters Patent.

L an interchangeable signet-plate, and -c the pointed end of a pin or similar article, as shown in Fig. 7.

The ring a has an oval box-shaped head a, in the bottom of which, adjacent one end, is the oF-center hole a2 and on the inner side wall of the head the annular ledge a3, having the off-center opening at, one side of which has'the beveled surface (t5, as shown in Figs. 5 and 7. Otherwise the ring may be of any design or configuration desired.

The signet-plate 7) is shaped to fit the head a of the ring and rest on the ledge a3 iiush with the face of the head. The face of the signet-plate is adapted to have a letter or monogram.- A frame is constructed to have the loop b2 at one end and the slot If in the opposite end. A spring-wire arm 7;" is secured adjacent the end br in the loop 722 of the frame 71 by solder or other means. This spring-arm 7;* extends centrally approximately the length of the plate, the free end passing through the slot If in the frame L', the length of the slot allowing a limited side movement only to the free end 216 of the spring-arm. The frame b is now secured to the under side of the plate by solder or other means in a position to bring the spring-arm Z2* on a central line lengthwise of the plate, as shown in Fig. 4. The lixed end b of the arm is adapted to go under the ledge as and the free end L to pass through the opening a* and snap under the ledge, thus securely locking the plate to the ring.

After a dealer has fitted a buyer with the size of ring desired adifferent letteror monogram is usually req uired. The signet-plate is easily removed from the ring by inserting the pointed end of a pin or similar article into the hole a2. The pointed end of the pin engages with the free end 7) of the spring-arm and moves it sidewise into the opening a* in the ledge against the spring tension of the arm, when a further inward movement of the pin will push the plate out of the ring. The new plate is now inserted by placing the fixed end 7F of the spring-arm b'tunder the ledge a3 opposite the hole (fand forcing the plate into the head of the ring. As the plate enters the head of the ring the free end of the springarm b" strikes the beveled surface a5, which forces the end of the arm sidewise into and through the opening' when it snaps under the ledge a3, as shown in Figs. 5 and 7, and automatically locks the signet-plate to the ring.

lt is evident that the head oi' the ring and the signet-plate could be of any configuration desired Without materially aecting the spirit of my invention.

Havingthus described my invention, I claim as new and desire to secure by Letters Patent- 1. A linger-ring having a box-shaped head in the bottom of which is an oil-center hole adjacent one end and a ledge on the inner side walls ot' the head having an opening one side of which is beveled, a signet-plate having a spring-arm, and means for securing one end of the spring-arm to the under side of the plate in a position for the fixed end of the arm to go under the ledge and for the free end of the arm to lirst strike the beveled surface, pass through the opening in the ledge, and snap under the ledge, as described.

2. A finger-ring having' a box-shaped head in the bottom of which is an ott-center hole adjacent one end and a ledge on the inner side Walls ot' the head having an opening one side of which is beveled, a signet-plate, a springwire arm, a frame having a loop, means for securing one end of the spring-Wire arm in the loop of the frame, and means for securing' the frame to the under side of the signet-plate in a position for the lixcd end of the springarm to go under the ledge and for the free end of the .spring-arm to first strike the beveled surface, pass through the opening in the ledge and snap under the ledge, thereby locking the signet-plate to the ring, as described.

3. The combination of a finger-ring a having the box-shaped head a in the bottom of which is the oli-center hole a2 adjacent one end, and the ledge a3 on the inner side wall of the head having the opening a4 one side of which has the beveled surface at, afsignetplate I; shaped to lit in the head of the ring, a frame constructed to have the loop on one end and the slot 3 in the opposite end, a spring-wire arm b4, means for securing' the spring-arm L4 adjacent one end in the loop b2 of the frame in a position for the vfree end b" to extend through the slot 3 in the frame, and means for securing the frame 7;' to the under side of the signet-plate?) in a position 'for the iiXed end f of the spring-arm to go under the ledge fand for the free end blof the arm to first strike the beveled surface all, -pass through the opening t4 in the ledge and snap under the ledge, thereby locking the signetplate in the head of the ring, as described.

In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.

FRED M. ALLEN.
